I am working on a top using the latest Missouri Star quilting tutorial and 2 10 inch fabrics. I would chose the muslin and the feed sack. They are sewn together and cut in such a way that there is a small pinwheel in the center of the churn dash. MUCH more interesting and really fun to make.
I am off to work and do not have time to look up the website but I bet someone else here can find it. I love this block.
